Man, Clutch is awesome! They're a favorite of mine. I definitely like their later stuff more, though. They began to hit their stride with Pure Rock Fury, and after that everything is just gold. But I love the debut as well. The self-titled is their weakest, in my opinion; it was clear they were having a bit of an identity crisis at that point, straddling the line between the more stoner rock, bluesy stuff and the heavier, angrier stuff from the first album and demos and whatnot. Awesome band, though.
They need to cover a ZZ Top song, too!
